摘要
2016年2～12月,对淠河湿地进行了实地调查,通过采集标本、拍照和查阅相关文献,采用双向指示种分类和主成分分析方法,对淠河10个样地的70个样方进行分类排序。结果表明,在70个样方中,共记录67种植物物种。淠河湿地植被丰富,其植物群落可以划分为水域植物群落、沼生植物群落和洲滩植物群落;对70个样方排序,可以划分出15种植物群丛类型;淠河湿地的珍稀濒危植物有野大豆（Glycine soja）、野菱（Trapa incisa）、金荞麦（Fagopyri cymosi）、香樟（Cinnamomum camphora）、鹅掌楸（Liriodendron chinensis）、莲（Nelumbo nucifera）、水杉（Metasequoia glyptostroboides）、银杏（Ginkgo biloba）,其中后5种为栽培种;淠河湿地外来入侵植物有11科18种,其中,13种来源于美洲,占72.2%,9种来源于北美洲。
The field investigation was in Pihe River wetlands during February to December in 2016. Samples were collected; the pictures were taken; and related literature was obtained, and using TWINSPAN and principal component analysis methods, 70 quadrats at 10 sampling sites were sequenced. The results showed that 67 dominant plant species were found in 70 quadrats. There were rich plants in the Pihe River wetlands, the plant communities surveyed could be categorized into the aquatic plants, marshy plants and mesophyta communities. The plants in 70 quadrats could be classified as 15 plant associations in the wetlands; at the same time it endangered plants Glycine soja, Trapa incise, Fagpyri cymosi, Cinnamomum camphora, Liriodendron chinensis, Nelumbo nucifera, Metasequoia glyptostroboides, Ginkgo biloba. The latter five species were cultivated.In the Pi River wetlands, 18 species were alien invasive species belonged to 11 families, among them, the sources of 13 species were in the Americas, accounted for 72.2%, while 9 species were in the North America.
